What is it?

Isolated wide voltage range interface board that allows Raspberry Pis, Arduinos or any digital input to monitor a wide range of AC/DC voltages (12V, 24V, 48V, or higher). It has a built-in LED to make it easy to see when a signal is active. Can also be used as an R-R voltage divider or R-R-C voltage divider with low pass filter.

Each order contains 2 bare circuit boards. What components are populated, and the values used are dependent on the application. Once we get an idea of the interest in this design and the most common applications, we may be able to offer kits with often used component values.

Why did you make it?

I use Raspberry Pis and Arduinos to monitor and control systems in agriculture and industry and wanted a versatile interface board that could be used in a wide variety of prototype and low volume situations.

What makes it special?

It can be populated in a number of different ways to accommodate a wide range of AC/DC voltages (12V, 24V, 48V, or higher) with and without optical isolation, with two mounting holes and screw cage connectors to provide a stable platform for interfacing external signals. A Zener diode provides surge clamping/regulation and a filter capacitor filters AC signals or can hold the voltage steady for A/D converters.

What is a Tindarian?

We recognize our top users by making them a Tindarian. Tindarians have access to secret & unreleased features.

How does one become a Tindarian?

We look for the most active & best members of the Tindie community, and invite them to join. There isn't a selection process or form to fill out. The only way to become a Tindarian is by being a nice & active member of the Tindie community!
